Taallwhomit'htdy'concerm Q Be it known that I, JUL'IUEYS( iHmNc K, of

Bierberhaus, Ernst Merclistrasses I-lamburg, G,e1many, a subject of theGerman Emperor, have invented certain new: and useful Improvements -'inthe Manufacture of Solid 4 Fatty Substances from" Oils, of which thefollowing is a specification.

' Thisinvention relates to the manufacture of solid fatty substances,and more particu-' larly' ediblefats, from oils. In this' respect. it isknown'that many metals in finely difatty acids and g1ycerid s'. ladiuminlpa'rticular have tion.

vided condition act'a's catalysts toefi'ect the combination of hydrogen:with unsaturatedhydrocarbons and also with unsaturated 'een proposed forthis purpose, the latter in colloidal condh By previous processes fattyacids and fats for industrial purposes'have been success.-

" fully hardened butJconside'i-able difficulties were incurred .inarranging the technical process so that'it could beused as far aspossible continuously for thef'manufa'cture of solid edible fats fromoils.

The object of the present invention is to provide such aprocess and itconsists .in passing the 0il in the thinnestfilm and over the catalystin the presence of hydrogen, and in such-a manner. that the saidcatalyst ofi'ers v ja'frictional resistance to the oil, the hydrogenbeing-supplied under pressure if necessary and in'case'of easilydecomposableoils or fats at a: temperat ranging o 0 200 deg es a a Theapparatus for carrying out the aboveprocess comprises a. centrifugaldrum closed at the top; capable'ofheing heated and hav-' ing an inletopening'for'the oil and hydrogen, perforated sie walls for holding the.

- catalyst, and a casing. with discharge op enrings for the hydrogenoverflow and for the, oil.

Methods of carrying out the processare shown diagrammatically in theaccompany! ing-drawing,'Figure 1 illustrating a form of apparatusembodying a single centrifugal in any suitable manner as by provid drum,and Fig. 2 a similar-view of an ap paratus embodying a plurality ofcentrifugal drums arranged in series.

; With the 'fOI'III'Of ap 1, the oil andflthe hy rogen are introducedthrough thejinlet pipe 6 into the centrifugal drum a which is'closed atthe top and can be Specification of. Letters Patent. Application filedDecember 9, 19 11'.

The temperature ofthe drum-c anditsgcasing is so regulatcd'that the fatis in moltencondition; The oil introducedinto the drum 4 isthusdriven'bycentrifugalforce through the side walls'of the' drum vwhere the oil is spread outinto the thinnest film and where-it simultaneously encounters a fairlysubstantialfrictional resistance the reaction with the hydrogen takes .pla'ce in The oil or fat then the most rapid manner-.- flows 'oflE'through d andaccording, to the degree to which-it is desired to hardenthe oil is led'ba'ck one'or more times into the drum 'by'means of pumps.The hydrogenwhich may be introduced under pressure ifkieces- ,sary, andwhich is discharged at 0 may also be led back'into the drum a. Theprocess 7 may also be carried out he 'row'of such centrifugal drumsarranged in series so that a uniform rocess takes place in thesuccessive drums. uch an'apparatus is illustrated diagrammatically in.Fig. 2jwhereinthe drums aare all mounted on a 'shaftfcon'stituting theEachdrum issurrounded by a jacket provided at the top with the outlete"-'- for the tom of each drum is \d-' for the oil. Both openings c andd lead from the to the feed pipe -b' of the next drum.

To this end, the openings- 0 ands-d2 arearranged to discharge into achamber -f-- surrounding the feed pipe b. If necessary, fresh hydrogenmay be fed into opening or channel c"- as: at A steam acket e',surrounds each 'drum a,as. in the apparatus embodying a a g e drum sothat the drums can be heated.

The supply of the oil and the arrangement of the drums preferably takesplace'in such a manner'that the hindmost contain the mostactivecatalyst. By regulation of the rotational motion or b utilizinga largeror e centrifugal apparatus the process. may be so adjusted that ondisjacket of one drum;

The hardening-of the oil in the drum goes onwith surprising. smoothness.

Sesameoil is particularly suitable for the hardening. It is notnecessary, in this instance that the hydrogen should be under pressure.'Industrial fats and fatty acids may be hardened .in a similar manner.

I claim: I

An improved processfor the manufacture of solid fatty substances,particularly edible fats, from oils, in which the oil in hquid conditionand in the thinnest film is passed by centrifugal force over a. catalystin the presence of hydrogen and in such a manner that the said Catalystoffers. a triotional resistance to the oil, substantially as described.

2. An improved process for the manufacture of solid fatty substances,particularly edible fats, from oils, in which the on V is passed bycentrifugal force over a catalyst in the presence of hydrogen and insuch a manner that the said catalyst offers'a frictional resistance tothe oil, the hydrogen beingsupplicd under pressure, substantially asdescribed.
